Emotion recognition is a long-standing research problem in Artificial Intelligence (AI). With the growing popularity of conversational AI research, the topic of emotion recognition in conversations has received significant attention from the research community [1]}, [2]}, [3]}. Identifying emotions in conversations is a core step toward fine-grained conversation understanding, which in turn is essential for downstream tasks such as emotion-aware chat agents [4]}, [5]}, visual question answering [6]}, [7]}, health conversations [8]}, [9]} and others.
